Vladimir Ozerov updated IGNITE-11210: ------------------------------------- Ignite Flags: (was: Docs Required) > SQL: Introduce common logical execution plan for all query types > ---------------------------------------------------------------- > > Key: IGNITE-11210 > URL: https://issues.apache.org/jira/browse/IGNITE-11210 > Project: Ignite > Issue Type: Task > Components: sql > Reporter: Vladimir Ozerov > Assignee: Vladimir Ozerov > Priority: Major > Fix For: 2.8 > > Time Spent: 10m > Remaining Estimate: 0h > > At the moment we have a lot of various cached stuff used for different SQL > types (prepared statements for local queries, two-step queries for > distributed queries, update plan for DML). > What we need instead of having multiple caches is to create common execution > plan for every query, which will hold both DML and SELECT stuff. Approximate > content of such a plan: > # Two-step plan > # DML plan > # Partition pruning stuff > # May be even cached physical node distribution (for reduce queries) for the > given {{AffinityTopologyVersion}} > # Probably {{AffinityTopologyVersion}} > Then we will perform a single plan lookup/build per every query execution. In > future we will probably display these plans in SQL views. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
